"Rated 9.5 ..the big test was the audio quality of the InSound. We connected our iPhone 4S to the device in order to test a variety of music that included Sleigh Bells, Foo Fighters, Mass Effect 3 Soundtrack and Lana Del Ray. The audio quality was exceptionally clear and the headphones produced a wide range of highs, mids and lows. Voices were extremely clear and we tested the headphones with some audio books that included the Ricky Gervais Podcasts... once again, clean audio. Compared to some higher end noise-cancellation headphones, the InSound produced some great audio quality, especially considering the price."
